Some say the life of saturated colors can be extended by first running this tool across the gel. Others argue this just provides a mechanical failure for the heat to start to melt the gel. http://www.controlbooth.com/forums/lighting/11753-stop-blowing-holes-my-gels.html

...The 'pouncing' of gel has been a practice used by many theater technicians over the years, often to the point of achieving a 'voodoo, black magic' result. The perfing of Apollo PerfGel does not weaken the material, but predisposes a specific tear route. I can't honestly say it aids in the cooling of the product without running the risk of selling snake oil.
